[0050] This utility model proposes a conveying sheet feeding device 1000.

[0051] Please see Figure 1 In one embodiment of this utility model, the conveying sheet feeding device 1000 includes a housing 1, a first film-taking mechanism 2, a second film-taking mechanism 3, and a recycling mechanism 4. The housing 1 has a feed inlet 11 and is equipped with a first conveying platform 12 and a second conveying platform 13. The first film-taking mechanism is located inside the housing 1 and is connected to the first conveying platform 12. The second film-taking mechanism is located inside the housing 1 and is connected to the second conveying platform 13, and is offset from the first film-taking mechanism along the height direction of the housing 1. The recycling mechanism 4 is located inside the housing 1 and is connected to both the first and second film-taking mechanisms. The recycling mechanism 4 is configured to collect the film material after the film-taking operations of the first and second film-taking mechanisms.

[0052] In this embodiment, the conveyor-type sheet material feeding device 1000 can be applied to scenarios such as the electronics manufacturing industry and the packaging industry. The following explanation uses the electronics manufacturing scenario as an example. It should be noted that an upper material film and a lower material film are respectively attached to the surface of the circuit board (material). To recover the upper and lower material films, a first film-retrieving mechanism 2 and a second film-retrieving mechanism 3 are provided to process the upper and lower material films respectively. The chassis 1 supports the entire device and has a feed inlet 11. Figure 1 It is understood that the chassis 1 has two feed ports 11, each feed port 11 corresponding to a conveyor platform. The first conveyor platform 12 is used to transfer material from one feed port 11 to the first film-taking mechanism 2, and the second conveyor platform 13 is used to transfer material from the other feed port 11 to the second film-taking mechanism 3. The implementation of the first conveyor platform 12 and the second conveyor platform 13 includes, but is not limited to, belt conveying, roller conveying, chain conveying, etc., and is not limited here. The first film-taking mechanism 2 is used to take film from the material transferred by the first conveyor platform 12, and the second film-taking mechanism 3 is used to take film from the material transferred by the second conveyor platform 13. The area where the first film-taking mechanism 2 performs the film-taking operation on the first conveyor platform 12 is called the first film-taking station 2a, and the area where the second film-taking mechanism 3 performs the film-taking operation on the second conveyor platform 13 is called the second film-taking station 3a. Combined with... Figure 1 It should be noted that the first film-taking mechanism 2 and the second film-taking mechanism 3 are staggered along the height direction of the housing 1, with the first film-taking mechanism 2 located above the second film-taking mechanism 3. The extension length of the first conveying platform 12 along the length direction of the housing 1 is less than the extension length of the second conveying platform 13 along the length direction of the housing 1. The shape formed by the first film-taking mechanism 2 and the second film-taking mechanism 3 in the housing 1 is roughly a trapezoid with its inclined sides. Furthermore, the structure of the first film-taking mechanism 2 furthest from the feed inlet 11 and the structure of the second film-taking mechanism 3 closest to the feed inlet 11 are on the same horizontal line. The recycling mechanism 4 is used to collect the upper and lower film materials after the film-taking operations of the first film-taking mechanism 2 and the second film-taking mechanism 3. The recycling mechanism 4 is located in the area where the feed inlet 11 is located. The recycling mechanism 4 is connected to the first film-taking mechanism 2 and the second film-taking mechanism 3 respectively, which can collect the film materials after the film-taking operation in a timely manner, and also makes the recycling of the film materials more centralized and orderly.

[0053] The conveyor-type sheet feeding device 1000 provided by this utility model solves the problems of efficiency, accuracy, and material management of traditional feeding equipment by adopting a specific layout and connection method of the housing 1, the first film-taking mechanism, the second film-taking mechanism, and the recycling mechanism 4. Specifically, the housing 1 is equipped with the first film-taking mechanism and the second film-taking mechanism, which are staggered along the height direction of the housing 1. This layout allows the two film-taking mechanisms to work simultaneously in the same housing 1 without interfering with each other, greatly improving film-taking efficiency and avoiding film-taking errors caused by mutual interference between the film-taking mechanisms. The first film-taking mechanism is connected to the first conveying platform 12, and the second film-taking mechanism is connected to the second conveying platform 13, ensuring that the material film can be smoothly transferred to the next process after film taking, improving the smoothness and stability of the entire feeding process. The recycling mechanism 4 is connected to the first film-taking mechanism and the second film-taking mechanism respectively, and can collect the material film after film taking in a timely manner, avoiding the loss and waste of material film, improving the utilization rate of material film, and reducing production costs. In addition, the centralized recycling management of recycling unit 4 makes the recycling of material film more orderly, which facilitates subsequent processing and reuse, and further improves the operating efficiency of the entire feeding equipment and the convenience of material management.

[0054] In one embodiment of this utility model, the recycling mechanism 4 includes a first recycling platform 41, a second recycling platform 42, and a third recycling platform 43. The first recycling platform 41 is connected to the first film-taking mechanism and the second film-taking mechanism, and is located between the first conveying platform 12 and the second conveying platform 13. The first recycling platform 41 is configured to collect the lower film of the first film-taking mechanism and the upper film of the second film-taking mechanism. The second recycling platform 42 is located below the second film-taking mechanism and is connected to the second film-taking mechanism. The second film-taking mechanism is configured to collect the lower film of the second film-taking mechanism. The third recycling platform 43 is located above the first conveying platform 12 and is connected to the first film-taking mechanism. The third recycling platform 43 is configured to collect the upper film of the first film-taking mechanism.

[0055] In this embodiment, combined with Figure 2 and Figure 3To achieve efficient recycling, the rational layout of three recycling platforms allows for the separate collection of the upper and lower film generated by the first film-taking mechanism 2 and the second film-taking mechanism 3 after their film-taking operations. This ensures high recycling efficiency and reduces material waste. The first recycling platform 41, located between the first conveyor platform 12 and the second conveyor platform 13, simultaneously collects the lower film from the first film-taking mechanism 2 and the upper film from the second film-taking mechanism 3. The second recycling platform 42, located below the second film-taking mechanism, specifically collects the lower film from the second film-taking mechanism 3. The third recycling platform 43, located above the first conveyor platform 12, specifically collects the upper film from the first film-taking mechanism 2. It is understood that the third recycling platform 43 is positioned above the first recycling platform 41, and the first recycling platform 41 is positioned above the second recycling platform 42. The third recycling platform 43 includes a roller 431 and a third recycling drawer 433. The roller 431 passes through the housing 1 and is driven by a third transmission component. This third transmission component can be, but is not limited to, a motor or cylinder; a motor, such as a servo motor or stepper motor, is preferred here. The first recycling platform 41 and the second recycling platform 42 are described in detail in subsequent embodiments.

[0056] In one embodiment of this utility model, the area formed by the first film-taking mechanism 2 on the first conveying platform 12 is the first film-taking station 2a. The first film-taking mechanism includes a first vacuum plate 21, a first film-suction assembly 22, and a first film-collecting assembly 23. The first film-suction assembly 22 and the first film-collecting assembly 23 are respectively provided on opposite sides of the first film-taking station 2a. The first film-suction assembly 22 and the third recycling platform 43 form a first limiting channel 2b for limiting the material to be placed on the film, and the first film-collecting assembly 23 and the first conveying platform 12 form a second limiting channel 2c for limiting the material to be placed on the film.

[0057] The area formed by the second film-taking mechanism 3 on the second conveying platform 13 is the second film-taking station 3a. The second film-taking mechanism includes a second vacuum plate 31, a second film-suction assembly 32, and a second film-collecting assembly 33. The second film-suction assembly 32 and the second film-collecting assembly 33 are respectively provided on opposite sides of the second film-taking station 3a. The second film-suction assembly 32 and the first recycling platform 41 form a third limiting channel 3b for limiting the material to be placed on the film, and the second film-collecting assembly 33 and the second conveying platform 13 form a fourth limiting channel 3c for limiting the material to be placed on the film.

[0058] In this embodiment, combined with Figures 1 to 3It should be noted that the first film-taking mechanism 2 is located above the first conveying platform 12. The area formed by the first film-taking mechanism 2 and the first conveying platform 12 is the first film-taking station 2a. The first film-taking station 2a includes a first vacuum plate 21, a first film-suction assembly 22, and a first film-collecting assembly 23. The first vacuum plate 21 is located below the first conveying platform 12. It can be understood that the first conveying platform 12 here is a belt-driven conveyor, that is, it includes two first pulleys and a first belt. The first vacuum plate 21 is located below the first belt, and both ends of the first vacuum plate 21 are fixed to the housing 1. The first film-suction assembly 22 is used to perform film-applying processing on the material on the first conveying platform 12, the second film-suction assembly 32 is used to perform film-applying processing on the material on the second conveying platform 13, the first film-collecting assembly 23 is used to perform film-removing processing on the material on the first conveying platform 12, and the second film-collecting assembly 33 is used to perform film-removing processing on the material on the second conveying platform 13. The first film suction assembly 22 is fixed at both ends to the housing 1. The first film suction assembly 22 is positioned near the third recycling platform 43, with a portion of its structure located above the third recycling platform 43. The first film collection assembly 23 is positioned at the end of the first conveyor platform 12 furthest from the feed inlet 11. The second film suction assembly 32 is fixed at both ends to the housing 1. The second film suction assembly 32 is positioned near the first recycling platform 41, with a portion of its structure located above the first recycling platform 41. The second film collection assembly 33 is positioned at the end of the second conveyor platform 13 furthest from the feed inlet 11. After the first film suction assembly 22 performs film loading processing on the material of the first conveying platform 12, the loaded film, driven by a portion of the structure of the first film suction assembly 22, moves from the first conveying platform 12 through the first limiting channel 2b to the third recycling platform 43. The first film receiving assembly 23 performs film unloading processing on the material of the second conveying platform 13, and the unloaded film, driven by a portion of the structure of the first film receiving assembly 23, moves from the second conveying platform 13 through the second limiting channel 2c to the first recycling platform 41, thus completing the film loading and unloading operation of the first film taking mechanism 2. It should be noted that during the film receiving process, the first film receiving assembly 23 uses a robotic arm to grip the intermediate material wrapped by the upper and lower films and transfer it to another area. The second film suction assembly 32 and the second film receiving assembly 33 of the second film taking mechanism 3 operate on the same principle as the first film suction assembly 22 and the first film receiving assembly 23 of the first film taking mechanism 2, and will not be elaborated further here. Figure 2 and Figure 3 It is understood that the first conveying platform 12 includes two first conveying wheels and a first conveyor belt, and the second conveying platform 13 includes two second conveying wheels and a second conveyor belt. The second limiting channel 2c is actually the channel limited by the first conveying wheel of the first conveying platform 12 and the first film taking-up assembly 23 at the end away from the feed inlet 11; the fourth limiting channel 3c is actually the channel limited by the second conveying wheel of the second conveying platform 13 and the second film taking-up assembly 33 at the end away from the feed inlet 11.

[0059] In one embodiment of the present invention, the first film suction assembly 22 includes a first adsorption member 222, a first film dispensing member 223 and a first driving structure 221. The first driving structure 221 is connected to the first adsorption member 222 and the first film dispensing member 223 respectively. The first adsorption member 222 is located above the first film taking station 2a, and the first film dispensing member 223 forms a first limiting channel 2b with the third recycling platform 43.

[0060] The first film receiving assembly 23 includes a second film-dispensing component 231 and a plurality of first pressure rollers 232. The second film-dispensing component 231 is configured to clean up the material. The plurality of first pressure rollers 232 are spaced apart along the width direction of the housing 1 and form a second limiting channel 2c with the first conveying platform 12.

[0061] In this embodiment, to achieve automated operation, the first film-taking mechanism 2, through the coordinated work of the first film-suction assembly 22 and the first film-collecting assembly 23, realizes automatic film taking and recycling of materials, reducing manual operation and improving production efficiency. The first drive structure 221 is connected to the first adsorption member 222 and the first film-dispensing member 223 respectively, in conjunction with... Figure 6 It is understood that the first adsorption member 222 is used to adsorb the upper film of the material, that is, to peel off the upper film; the adsorption method includes, but is not limited to, vacuum adsorption, electrostatic adsorption, etc., and vacuum adsorption is preferred here. The first adsorption member 222 is set on the first support 2212 of the first drive structure 221. Under the drive of the first drive structure 221, the first adsorption member 222 can move closer to or further away from the first film-removing station 2a. A connecting frame is also provided between the first adsorption member 222 and the first film-removing member 223. The connecting frame also has part of the structure of the first drive structure 221, so as to realize the movement of the first adsorption member 222 and the first film-removing member 223 along the extension direction of the first film-removing station 2a. The first film-removing member 223 is used to guide the transmission direction of the upper film of the material, ensuring that the upper film of the material does not deviate from the predetermined path during the recycling process. The first drive structure 221 is used to provide power and control the movement of the first adsorption member 222 and the first film-removing member 223. The first drive structure 221 can be of various types, including but not limited to motors and cylinders, but is preferably a motor. Power is transmitted to the first adsorption member 222 and the first deflector member 223 via gear or belt drive. Figure 8 The second film-dispensing component 231 is used to clean the material, ensuring that the film remains clean during the recycling process. After cleaning, the material is guided by multiple first pressure rollers 232 to ensure that the film does not deviate from the predetermined path during recycling. The second film-dispensing component 231 is positioned above the first conveying platform 12, forming a space between it and the first conveying platform 12 for the movement of the film. Figure 2 and Figure 3 It is understood that the first conveying platform 12 includes two first conveying wheels and a first conveyor belt. The second limiting channel 2c is actually a channel that limits the first conveying wheel of the first conveying platform 12 away from the feed port 11 and multiple first pressure rollers 232. The material on the first conveying platform 12 falls onto the first recycling platform 41 after passing through 2c, and is finally recycled to the first recycling drawer 413 of the first recycling platform 41.

[0062] In one embodiment of the present invention, the second film suction assembly 32 includes a second adsorption member 322, a third film-dispensing member 323, and a third driving structure 321. The third driving structure 321 is connected to the second adsorption member 322 and the third film-dispensing member 323 respectively.

[0063] In this embodiment, to achieve automated operation, the second film-taking mechanism 3, through the coordinated work of the second film-suction assembly 32 and the second film-collecting assembly 33, realizes automatic film taking and recycling of materials, reducing manual operation and improving production efficiency. The third drive structure 321 is connected to the second adsorption member 322 and the third film-dispensing member 323 respectively, in conjunction with... Figure 7 It is understood that the second adsorption member 322 is used to adsorb the film on the material of the second conveying platform 13, that is, to peel off the film; the adsorption method includes, but is not limited to, vacuum adsorption, electrostatic adsorption, etc., and vacuum adsorption is preferred here. The second adsorption member 322 is set on the second support 3212 of the third drive structure 321. Under the drive of the third drive structure 321, the second adsorption member 322 can move closer to or further away from the second film-taking station 3a. A connecting frame is also provided between the second adsorption member 322 and the third film-taking member 323. The connecting frame also has part of the structure of the third drive structure 321, so as to realize that the second adsorption member 322 and the third film-taking member 323 move along the extension direction of the second film-taking station 3a. The third film-taking member 323 is used to guide the conveying direction of the film on the material, ensuring that the film on the material does not deviate from the predetermined path during the recycling process. The third drive structure 321 is used to provide power and control the movement of the second adsorption member 322 and the third film-taking member 323. The third drive structure 321 can be of various types, including but not limited to motors and cylinders, but is preferably a motor. Power is transmitted to the second adsorption member 322 and the third deflector member 323 via gear or belt drive. Figure 9The fourth film-dispensing component 331 is used to clean the material, ensuring that the material remains clean during the recycling process. After cleaning, the material is guided by multiple second pressure rollers 332 to ensure that the material does not deviate from the predetermined path during recycling. The fourth film-dispensing component 331 is positioned above the second conveying platform 13, forming a space between it and the second conveying platform 13 for the material to move.

[0064] Combination Figure 2 and Figure 3 It is understood that the second conveying platform 13 includes two second conveying wheels and a second conveyor belt. The fourth limiting channel 3c is actually a limiting channel between the second conveying wheel of the second conveying platform 13 and multiple second pressure rollers 332 at the end of the second conveying platform 13 away from the feed port 11. After passing through 3c, the material on the second conveying platform 13 falls onto the second recycling platform 42 and is finally recycled to the second recycling drawer 422 of the second recycling platform 42.

[0067] In this embodiment, combined with Figure 6 and Figure 7 It is understandable that the first film-pulling component 223 and the third film-pulling component 323 are arranged in a U-shape, with the U-shaped opening facing the feed inlet 11, which can better wrap the material onto the film. At the same time, it can better form a stable first limiting channel 2b between the first film-pulling component 223 and the roller 431 of the third recycling platform 43; and form a stable third limiting channel 3b between the third film-pulling component 323 and the first recycling platform 41.

[0068] Combination Figure 8 and Figure 9It is understandable that the inclined second film-peeling member 231 and fourth film-peeling member 331 can separate the material from the lower film, thereby realizing the peeling operation of the lower film. The second film-peeling member 231 forms an acute angle with the surface of the first conveying platform 12; its shape is generally ∠, that is, the pointed part of the second film-peeling member 231 extends under the material to realize the peeling operation of the lower film. The fourth film-peeling member 331 forms an acute angle with the surface of the second conveying platform 13, and its shape is generally ∠.

The second driving member 2213 can drive the first film-removing member 223 to move along the extension direction of the first film-removing station 2a.

[0070] Alternatively, the third driving structure 321 includes a third driving member 3211, a second support 3212, and a fourth driving member 3213. The third driving member 3211 is installed in the housing 1, and the driving end of the third driving member 3211 is connected to the second support 3212. The second adsorption member 322 is installed in the second support 3212, and the fourth driving member 3213 is installed in the second support 3212.

The fourth driving member 3213 can drive the third film-dispensing member 323 to move along the extension direction of the second film-dispensing station 3a.

[0071] In this embodiment, combined with Figure 2 It should be noted that, in order to precisely control the positions of the first adsorption member 222 and the first film-dispensing member 223, the first driving member 2211 is installed through the housing 1 and located on one side of the housing 1.

[0073] In one embodiment of the present invention, the first vacuum plate 21 has a plurality of spaced first waist-shaped holes 211, which are connected to form a plurality of first air intake channels 212, and each first air intake channel 212 is connected to a first vacuum reactor; the second vacuum plate 31 has a plurality of spaced second waist-shaped holes 311, which are connected to form a plurality of second air intake channels 312, and each second air intake channel 312 is connected to a second vacuum reactor.

[0074] In this embodiment, combined with Figure 10 and Figure 11To achieve uniform adsorption, multiple spaced first oblong holes 211 and second oblong holes 311 ensure that the adsorption force is evenly distributed across the entire vacuum plate. This prevents material interference during the adsorption process of the first adsorption element 222 of the first film adsorption assembly 22 and the second adsorption element 322 of the second film adsorption assembly 32. The arrangement of the first oblong holes 211 and second oblong holes 311 provides a larger adsorption area while reducing the concentration of adsorption force, preventing the material from being subjected to excessive local pressure during adsorption. Multiple first oblong holes 211 are interconnected to form multiple first air inlet channels 212, each of which connects to a first vacuum reactor; multiple second oblong holes 311 are interconnected to form multiple second air inlet channels 312, each of which connects to a second vacuum reactor. A vacuum pump generates negative pressure, adsorbing the material onto the first vacuum plate 21 and the second vacuum plate 31 respectively. Each first air intake channel 212 is connected to a first vacuum reactor via a pipe or hose, and each second air intake channel 312 is connected to a second vacuum reactor via a pipe or hose, ensuring the sealing and reliability of the connection.

[0075] In one embodiment of the present invention, the first film suction assembly 22 includes a plurality of first adsorption elements 222, and each first adsorption element 222 is spaced apart along the width direction of the housing 1 on the first support 2212 of the first drive structure 221; the second film suction assembly 32 includes a plurality of second adsorption elements 322, and each second adsorption element 322 is spaced apart along the width direction of the housing 1 on the second support 3212 of the third drive structure 321.

[0076] In this embodiment, to achieve uniform adsorption, multiple first adsorption elements 222 and multiple second adsorption elements 322 are respectively spaced along the width direction of the housing 1 on the first support 2212 of the first driving structure 221 and the second support 3212 of the third driving structure 321, ensuring that the adsorption force is evenly distributed on the entire upper film of the material. Combined with... Figure 6 and Figure 7 It is understood that the first adsorption element 222 is symmetrically arranged on both sides of the center of the first support 2212, and the second adsorption element 322 is symmetrically arranged on both sides of the center of the second support 3212. The first adsorption element 222 or the second adsorption element 322 can be connected to the vacuum pump via pipes, air inlet connectors, etc., to ensure the sealing and reliability of the connection. It should be noted that the first adsorption element 222 can be mounted on the first support 2212 via threaded connection, flange connection, welding, etc. In one embodiment, the first support 2212 has an insertion hole, the size and shape of which are adapted to the connection end of the first adsorption element 222, and the first adsorption element 222 is fixed to the first support 2212 through the insertion hole. The arrangement of the second adsorption element 322 is similar to that of the first adsorption element 222, and will not be elaborated further here.

[0077] In one embodiment of the present invention, the first recycling platform 41 includes a fifth driving member 411, a first recycling belt 412 and a first recycling drawer 413. The fifth driving member 411 is connected to the first recycling belt 412 in a transmission manner.

[0078] The second recycling platform 42 includes a sixth driving component, a second recycling belt 421 and a second recycling drawer 422. The sixth driving component is connected to the second recycling belt 421 in a transmission manner. The second recycling belt 421 is connected to the second film taking mechanism and the second recycling drawer 422 respectively.

[0079] The third recycling platform 43 includes a roller 431, a seventh drive component 432, and a third recycling drawer 433, which are installed in the housing 1. The roller 431 connects the first film-taking mechanism 2 and the third recycling drawer 433, and the seventh drive component 432 is connected to the roller 431 in a driving manner.

[0080] Alternatively, the first conveying platform 12 may have a first base plate; the second conveying platform 13 may have a second base plate.

[0081] In this embodiment, to achieve efficient recycling, the materials from the first film-taking mechanism 2 and the second film-taking mechanism 3 can be processed simultaneously through the first, second, and third recycling platforms 43, thereby improving recycling efficiency. Combined with... Figure 2 and Figure 3 It can be understood that the fifth driving component 411 drives the first recycling belt 412 via a transmission connection, realizing the movement of the first recycling belt 412 and realizing the recycling of materials into the first drawer. The sixth driving component drives the second recycling belt 421 via a transmission connection, realizing the movement of the second recycling belt 421 and realizing the recycling of materials into the second recycling drawer 422. Combined with... Figure 4 The roller 431 rotates, thus collecting the material to the third recycling drawer 433. It should be noted that the first recycling platform 41 is a component jointly used by the first film-receiving mechanism 2 and the second film-receiving mechanism 3 to collect the film. The first recycling platform 41 collects not only the lower film from the first film-receiving mechanism 2 but also the upper film from the second film-receiving mechanism 3. The second recycling platform 42 is used to collect the upper film from the first film-receiving mechanism 2. The third recycling platform 43 is used to collect the lower film from the second film-receiving mechanism 3. Specifically, the types of the fifth driving member 411, the sixth driving member, and the seventh driving member 432 include, but are not limited to, cylinders and motors; here, a motor is preferred. Figure 3It should be noted that the fifth drive component 411 of the first recycling platform 41 is actually a drive motor and two first recycling wheels. The two first recycling wheels are connected by a first recycling belt 412. A third limiting channel 3b is formed between the first recycling wheel of the second film suction assembly 32 near the second film taking mechanism 3 and the third film pushing component 323 of the second film suction assembly 32 for limiting the film loading of materials on the second conveying platform 13. The sixth drive component of the second recycling platform 42 is actually a plurality of second rollers and a drive motor. The second rollers are arranged along the extension direction of the housing 1, and the second roller closest to the feed inlet 11 is connected to the second recycling drawer 422.

[0082] Furthermore, to support and stabilize the first conveyor belt of the first conveyor platform 12 and the second conveyor belt of the second conveyor platform 13, a first base plate is provided inside the first conveyor platform 12; and a second base plate is provided inside the second conveyor platform 13. These base plates not only provide solid support for the conveyor belts, but also effectively reduce vibration and deviation that may occur during material transfer, thereby significantly improving the stability and operating efficiency of the entire transfer system.

[0083] In one embodiment of the present invention, the conveying sheet feeding device 1000 further includes at least two sensors, which are respectively set for the first film taking mechanism and the second film taking mechanism, and are both located on the side of the first film taking mechanism away from the feed inlet 11 and the side of the second film taking mechanism away from the feed inlet 11.

[0084] In this embodiment, it should be noted that the types of sensors include, but are not limited to, photoelectric sensors, proximity switches, and laser sensors, with photoelectric sensors being preferred. It should also be noted that one of the two sensors is a first sensor, located at the first film receiving assembly 23 of the first film-taking mechanism 2, used to detect the position of the material on the first conveying platform 12; the other of the two sensors is a second sensor, located at the second film receiving assembly 33 of the second film-taking mechanism 3, used to detect the position of the material on the second conveying platform 13. This arrangement, through sensor feedback, allows the control system to automatically adjust the actions of the film-taking mechanism, improving film-taking efficiency and reducing film-taking errors caused by inaccurate positioning.

[0085] It should be noted that the operation of the entire equipment is explained using the first film-removing mechanism 2 as an example. First, the material enters the first conveying platform 12 through the first feed inlet 11 and moves to the first film-removing station 2a under the conveying of the first conveying platform 12. At this time, the first film-removing mechanism 2 performs film removal operation on the material at the first film-removing station 2a. The first film suction component 22 starts to work. Driven by the first driving component 2211, the first suction component 222 and the first film-dispensing component 223 are adjusted to the appropriate position. The first suction component adsorbs the film on the material. After adsorption, the film on the material passes through the first film-dispensing component 223. At this time, the roller 431 of the third recycling platform 43 starts to rotate, thereby rolling the film on the material to the first limiting channel 2b and dropping it into the third recycling drawer 433 of the third recycling platform 43, thus completing the recycling process of the film on the material. After the material is peeled off and coated, it continues to move under the conveying of the first conveyor platform 12. At this time, the first film receiving assembly 23 starts to work. The lower film passes through the sharp corner of the second film-dispensing component 231, and the material separates from the lower film. The material is then picked up by a robotic arm. The lower film continues to move on the first conveyor platform 12 and is rolled into the second limiting channel 2c by the limiting of multiple pressure rollers. As the first recycling platform 41 continues to rotate, the lower film moves onto the first recycling belt 412. Under the movement of the first recycling belt 412, it falls into the first drawer of the first recycling platform 41, thus completing the recycling process of the lower film. At this point, the film picking and recycling operations of the entire equipment are completed.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
